From owners

Pros, cons & observations

Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.

Tire A Bridgestone Potenza S01

The Bridgestone Potenza S01 is widely regarded as a high-performance tire that prioritizes exceptional grip and handling dynamics over longevity and comfort. While enthusiasts appreciate its uncompromising performance in both wet and dry conditions, users should be prepared for rapid tread wear and a firm, noisy ride quality.

Pros

  • Exceptional grip levels in both wet and dry conditions
  • Superior handling characteristics favored by performance-oriented vehicles
  • High-speed stability and performance consistency

Cons

  • Very rapid tread wear and short lifespan
  • High levels of road noise
  • Stiff and uncomfortable ride quality

Observations

  • Performance-focused vehicles like the Mitsubishi Evo 6 highlight the tire's tendency to wear out in sync with aggressive service intervals.
  • Porsche OEM N-Spec variants are noted for being intentionally uncompromising, designed specifically to complement sport-tuned suspensions.
Tire B Michelin Primacy 4

The Michelin Primacy 4 is widely regarded as a premium, long-lasting touring tire that excels in comfort, noise reduction, and consistent wet-weather performance. While it is highly praised for its longevity and safety, some enthusiasts find its handling 'floaty' or lacking in road feedback compared to sport-oriented tires, leading to a polarized experience depending on driving style.

Pros

  • Exceptional tread life and longevity
  • High levels of ride comfort and low road noise
  • Consistent performance even as the tire wears
  • Strong wet-weather grip and aquaplaning resistance

Cons

  • Vague steering feel and lack of road feedback
  • Soft sidewalls can feel 'mushy' or 'floaty' during spirited driving
  • High price point compared to competitors
  • Increased noise levels as the tire ages

Observations

  • Users with heavier vehicles or EVs often report a 'floaty' sensation, which some mitigate by increasing tire pressure.
  • Drivers of performance-oriented hatchbacks often find the tire's touring-focused design disappointing compared to UHP alternatives.
  • The tire is frequently noted for transforming the ride quality of vehicles previously fitted with harsh run-flat tires.

“Review: Michelin Primacy 4 ST I own a 2023 N8 DCT and recently changed all four tyres from the stock CEATs after one of the tyres’ sidewall was punctured on hitting a rather deep pothole at high speed. Cost: INR 9,750 per tyre Existing tyre buyback: INR 1,000 per tyre (~15k kms) Review: I’ve been using the new tyres for a few weeks now and I’m happy with the upgrade. The difference is noticeable, but only if you pay attention. I’d say a non-savvy person won’t notice anything different unless you ask them to pay attention. At low speeds, the road noise is reduced and the vehicle is noticeably silent (almost dead silent if the roads are smooth and the engine is at low revs) and smoother. At high speeds, the noise level difference is not very noticeable due to the engine and wind noise, but the smoothness and grip is noticeably better. That said, I wouldn’t say the stock tyres are bad (in terms of both - noise and grip) as a lot of reviewers like to point out; definitely not a night and day difference for me. Lastly, I believe the fuel efficiency has improved due to the lower rolling resistance, but I don’t have enough data to claim this confidently. My verdict is to only upgrade if your current tyres are worn out. Personally, I don’t think spending close to 40k is worth it for the budget conscious. But if you have the money to spare, you will definitely be happy with the upgrade. Read more”

“Am avut primacy 4 pe o electrica. Destul de dezamagit de faptul ca dupa ~ 28.000 km s-au tocit rau de au ajuns cam la 3 mm. Placute la condus, silentioase, dar nu cele mai aderente. Pilot sport 4 pe aceiasi electrica cu primacy 4. Huruie de te doare capul. Aderenta nu o simt neaparat wow fata de primacy 4. Nu le mai suport si abia astept sa le trec pe iarna, oricum asta fiind ultima incaltare cu ele. Pe o termica am primacy 5, si sunt cele mai ok din experienta mea. Cele mai silentioase si aderente din cele 3. Dupa 20.000 km uzura a scazut cam cu 1 mm. Recomandarea mea e sa alegi primacy 5 fara ezitare.”

“Both our Polestar2 (new) and 2016 Leaf (Jap import) arrived with Primacy 4s on them. The FWD Polestar needed fronts replaced at ~35k km and being 245/45 R19s Primacy were too pricey so went with Kumho Ecsta PS71 equivalents for a lot cheaper and negligible difference in performance. The rears on the Polestar are still going strong at 45k km and look like at least 60k km will be likely. We also fitted Kumhos on our previous Leaf and were very satisfied with performance and life.”

“When I bought my freshly imported 2014 Nissan Leaf in Sept 2020 it had 27,xxx km on the odometer and a full set of Michelin Primacy 4 that were sidewall dated from very late 2018, so likely only very low mileage on them. I put another 47,000km on them before replacing with a full set of Toyo Proxes C100 Plus in April 2024 which have also been great. The Michelin fronts were certainly very worn particularly the shoulders. I really rate Toyos so would encourage you to have a look. I’ve since put 21,000km on the Toyos and even after 12,500km, in May 2025 at their most recent WOF, the fronts still measured at 7mm and rears 8mm. P.S I paid $900 total for the 4 x Toyos inc. fitting, disposal etc.”

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements) normalized against the best tire in each test and weighted toward recent tests. 40% comes from thousands of owner reviews collected from retailers and review sites. When a tire has only one of the two, we use what exists and say so.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
